I am looking for an efficient and straightforward way how to count time on an MU from the first entry of the production line until being sent to the output storage (Ausgangslager).I thought about an user-defined Attribute and maybe using a sensor;but currently all MUs are moved via method, not transportation path, so I am not sure how to place the sensor;OR how to write this in a method in the exit strategy of the source and the entry strategy of the output storage to call this timer and to stop it again (and return the value on a list).
